in 1 gallons (4 quarts) of tap water to insure 600 PPM of available chlorine.

IMPORTANT: Use tap water at 75‐95°F (23.89‐35°C). Water above this range breaks down the chlorine count and minimizes sanitation.

Unit Foam Head Height Adjustment

NOTE: Follow all previous INSTALLATION and CLEANING/SANITATION section processes before continuing with this section.

Once the equipment has been installed, cleaned, and sanitized, perform the procedure in Table 5 to adjust the foam head height on the CNB BIB unit.

Table 5.

Step Action

1

Make sure the Nitrogen tank is open or the nitrogen gener‐ator is turned on.

The primary side gauge should be between 500 and 2500 PSI and the secondary gauge should between 60 and 80 PSI.

2 Open the cabinet door.

3Inside the cabinet, ensure that the Nitrogen inlet valve is turned to the “ON” position.

4

A. Open/remove Nitrogen secondary regulator access cover.

B. Locate the secondary Nitrogen regulator.Adjust only the regulator shown.



5

REDUCED FOAM HIGHT adjustment:

A. Adjust the regulator control knob slightly (approxi‐mately 1/8th of a turn) to the LEFT (counter‐clockwise). Only very fine adjustments are required. This reduces the amount of Nitrogen injected.

B. Open the RIGHT tower dispenser and dispense about 8 oz. of product to drain the line of product at the previ‐ous foam setting. Then dispense 12 oz. of product and confirm the foam head height. Repeat and dispense another 12 oz. to confirm setting.

C. Repeat step A if a further reduction of foam head height is required.

6

INCREASED FOAM HIGHT adjustment:

A. Adjust the regulator control knob slightly (approxi‐mately 1/8th of a turn) to the RIGHT (clockwise). Only very fine adjustments are required. This increases the amount of Nitrogen injected.

B. Open the RIGHT tower dispenser and dispense about 8 oz. of product to drain the line of product at the previ‐ous foam setting. Then dispense 12 oz. of product and confirm the foam head height. Repeat and dispense another 12 oz. to confirm setting.
